Products Overview
Gracyfiber’s high-isolation single-mode FWDM device is specifically designed for GPON/XGS-PON + CATV FTTH networks, effectively separating the 1310 nm data signal from the 1550 nm video signal. Featuring high isolation of 45 dB and ultra-low insertion loss of ≤0.3 dB, this product is ideal for large-scale deployments and is available in flexible packaging options to meet diverse customer requirements..
